Determining Video Pixel Size from Still Pixel Sizes

Hello
I posted a few questions here in regard to establshing good Pixel Sizes in stills for use in FCE.
Tom, and Studio X were very helpful, and I picked up a few pointers.
One thing I still didn't grasp completley was how to determine (perhaps from a simple formula), what the Video Pixel Size would be from a photo's pixel size.
As Tom pointed out:
"A 2400x3000 pixel image may be perfectly adequate and not produce as many imaging problems when scaled in a video application"
And as I discovered in regard to print size:
"An 8" x 10" document that is scanned at 300 dpi has the pixel dimensions of 2,400 pixels (8" x 300 dpi) by 3,000 pixels (10" x 300 dpi).
So then all this being said, is there a way to easily determine what the Video Pixel Size will be from the given Pixel dimensions of a still image?
(Like from a re-sized Tiff in Photoshop)
My version of Photoshop doesn't seem to have that conversion option for determining NTSC Video image quality.
Thanx
Mike

And if I need to zoom in really tight to a small area in a particular still, I should allow myself an image size a bit larger than 1280x720. Correct?< </div>
If only it was that easy. The video screen is roughly 800 by 500 pixels. That's all there are. If you bring in a 1600x1000 JPEG (might want to try TIFF instead) and you wish to see the whole image, it will be scaled down to 25% to fit onto the small screen and all of your pixels will be thrown away or mashed together. It's terribly inefficient and the image gets mushily softened.
If you need to zoom in to a particular spot on the image, imagine that spot as filling the 800x500 pixel screen. You can use a simple ruler and measure the area you wish to be full screen (without any scaling being applied by FCP because that will destroy your image). Now measure the largest part of the image that you want to be on screen at any one time when zoomed all the way out. The ratio of those two numbers is what you will need to scan. Example (highly simplified don't try to argue about the precision) if your big image is 10x8 inches and your desired tight shot is 4x3 inches, you must provide a TIFF that is 2.5 or 2.75 times the size of the tightest area. That tight area is going to be 800x500 pixels. You will scan the 10x8 image to obtain a TIFF that is almost 2.5 times 800 pixels wide or 2000 pixels, by 2.5 times 500 pixels high or 1250 pixels. Do not bother to convert that into DPI. You are targeting an image size measured in pixels. It's got nothing to do with the size of the original image or the DPI. Repeating: Absolutely nothing.
This will give you an image into which you can zoom and suffer no image degradation. It will also give you a tremendous processing hit. FCP just doesn't like to do that kind of scaling.
Umm, doesn't look like I helped much. This issue is highly misunderstood and it's quite confusing if you come from a Photoshop background. giving up concepts like DPI is almost impossible. The only way to get it is to work through the many options Photoshop and video people offer up and try to figure out why some of them don't work for you.

Check the pixel size on runtime

Hi all
can any one tell me is there is any trigger which check the pixel size of user screen???i am using oracle 9iIDS and run on LAN....the problem is that i have create the form on pixel size 1024x768....now some user on LAN has pixel size 800x600...so the problem is that the forms doesn't look better on that pixel....i want that when form run it check the pixel size....if it is 1024x768 then ok if it is 800x600 then it prompt a message that u change ur pixel size to 1024x768.....
Is it possible to do????
plz reply
thanks in advance

now i am using this code
declare
al_button alert := find_alert('pixel');
al_id number(5);
width number(5) := get_application_property(display_width);
height number(5) := get_application_property(display_height);
LC$Scoord VARCHAR2(100) := Get_Form_Property( Name_in('system.current_form'), COORDINATE_SYSTEM ) ;
begin
-- Conversion of offset in pixel --
If LC$Scoord = 'INCHES' Then
width := width * 0.0104 ;
height := height * 0.0104 ;
ElsIf LC$Scoord = 'POINTS' Then
width := width * 1.333 ;
height := height * 1.333 ;
ElsIf LC$Scoord = 'CENTIMETERS' Then
width := width * 0.0263 ;
height := height * 0.0263 ;
End if ;
if width = 600 or height = 800 then al_id := show_alert(al_button);
end if;
end;
that code compile successfully but not give the alert if pixel is 800x600

How do I find the pixel size of a photo?

I have taken a photo or found one online.
It's now on my ipad.
How do I tell the pixel resoution of the photo via the ipad?
I have two of the same photos on my device at the moment and want to delete one. They may both be 2048/2048, but without emailing them or putting them in Dropbox, and viewing on my laptop, I don't see how to tell.

Get the Actual Pixels App from the App Store. It's free and will tell you the pixel size of any photo you open.

How do I get the pixel size at 100% on Photoshop CS6 to match the pixel size that will appear on web

I have a 500px x 500px document open but the size that it looks on Photoshop at 100% does not match the size that is 500px on the web. How do I change it on Photoshop CS6 so that it will give me an accurate display of the pixel size?
(I don't know if this needs to be mentioned but I am working on the new macbook pro and just downloaded the new photoshop update for retina displays).
Thank you in advance!!!

Ask in teh PS forum. Generally, though, pixels are pixels. Perhaps you simply have things backwards - as far as I know by default Safari doubles image sizes on Retina devices, which can lead to such discrepancies. There's an option for that in the prefs.

How do I change the pixel size of my photos?

Hello,
Please give me step by step instructions on how to change the pixel size of my photos from the time I log in.
Thank you.

There are basically two ways.
Image>Image Size... This will adjust the quality of the image, allowing you to adjust the pixel dimensions and keep the full image.
In the tool bar on left side of screen 5th icon down looks like a sliding picture frame. That is the crop tool, that will adjust the pixel size of a document by removing a portion of the image, allowing you to get rid of portions of the image you do not want.
There are some other ways to accomplish the above, but these are the basics that everyone needs to know. I recommend playing with these tools on a copy of an image, that way you won't be afraid of destroying an image.

HT3805 How can I adjust the pixel size of a photo

I wish to upload pictures to a site and they have requested min size 40 x 40 max size 200 x 200 I assume this is pixel size but can find no way of doing this in Aperture.
Surely this is a common enough request?

Use the file export command (Shift-Command-E), adjust the size to whatever you want.
You can make your own preset by pressing the + sign on the lower left corner.
If you forget any of this, just use Apertures Help screen:

Is there a way to determine pixel size of type displayed in browser?

I'm still wrestling with getting type to line-break as I see it in Dreamweaver.
At 'Actual Size' in Safari, the type is bigger than I see it in Dreamweaver. I have determined that 12px is the appropriate size while working in Dreamweaver but when I view the text online it is much bigger and the line-breaks do not fall where the writer wants them to.
Here is the page in question:
http://www.kgngroup.net/logos_and_packaging.html
I guess I was wondering first, if there is a 'sizeometer' that can identify the actual pixels size of type as it is displayed, so I can tell how much bigger it actually is than what I am trying to build.
TIA,
Ken

Hi
The size of your text is set to 100% in your body elements css, this means that for Safari you will get a default font size of 16px, (providing you have not changed the browsers default settings).
Change the body element font-size to 12px in the css and see what happens.

I've run out of helpful stars to hand out to all of you nice people. Thank you so much, and as the post quoted here also demonstrates, there are 'overrides' in CSS. It struck me this morning as I have been thinking about this, the very first thing to introduction to CSS is that the meaning of Cascading Style Sheets is that there is an order of priority in command, and the troops closest to the front lines get the final say. I would think that the statement in the document would be the final word, but apparently it's the CSS sheet that takes priority in this case.
I think my thinking has been in reverse on this rule, not unusual for me, but now I need to re-educate myself thanks to this problem.

Illustrator and Photoshop's stroke appearing larger then the pixel size I put.

My strokes in Illustrator and Photoshop CS6 are showing up larger then the pixel size that I put in. I checked my settings and nothing looks out of the norm. What could be causing this problem?

You can translate between points size and pixels size using the DPI:

Exporting Versions to a specific pixel size

I want to export files for a slideshow that requires a pixel size of 1900 x 1200 , can it be done in Aperture ? , I have tried modifying the export preset , it does not work with (Fit Within ) is there another way ?
Thanks
Ray

Trythis,
What exactly is failing?
Your 1900x1200 size is a very strange size. That's not the 3:2 aspect ratio of an SLR or the 4:3 aspect ratio of point-and-shoot cameras. Also, Aperture will not enlarge pictures by choosing "fit within", since a smaller picture already "fits within". I.e., if you have a 640x480 picture, that already "fits within" 1900 pixels so Aperture will not make it bigger.
Also, Aperture will not crop your pictures on export. You may have to crop each picture first so that it has a 19:12 aspect ratio, and then "fit within" 1900 pixels. If the aspect ratio of a picture is 19:12 and the picture is larger than 1900 pixels, Aperture should properly reduce the size to 1900x1200, based on the aspect ratio.

Is there a way to reduce the pixel size of multiple photos in a slideshow?

I have a Windows 7 computer and use Photoshop Elements 9 and Premiere Elements 9. I recently completed a slideshow that contains about 360 photos, many or all of which exceed the maximum size of 1000 x 750 pixels. Is there any way that I can easily reduce the pixel size of each of the photos? If upgrading to the most recent versions of Photoshop Elements and Premiere Elements would help me accomplish this I would be willing to do this. Thanks very much in advance for any advice or suggestions.

You can batch process your images to re-size them in the editor using the menu:
File >> Process Multiple Files
Place your chosen photos in a separate folder and then choose a separate destination folder; so as not to overwrite the originals.

This may be a basic question... but in InDesign, how does one determine the pixel size of a text box? Specifically, we need to write text to specifications of 600 pixel width, and have no idea a) how to scale a text box to specific pixel width, b) how to determine what word count we can fit in, and c) how to do it in a table? Thanks!

Set your ruler increments to pixels Preferences>Units & Increments. You can fill the text box with placeholder text Type>Fill with Placeholder text and get a word count from the Info panel with Show Options turned on from the flyout.
From the Transform panel you can set a text box's width and height

How do I change the pixel size when converting Word doc to .pdf?

When converting a Word Document to .pdf the file size is too large. How do I reduce the pixel size?

Typically a Word file's content is text which has not image association.
For whatever images might be in the Word file you'd want to adjust image resolution in an image editor prior to bringing the image into the Word file from which the PDF is made.
Be well...

My crop tool in CS5 does not give the option to crop by pixel size

How do I get the crop tool to give me the option of cropping by specific pixel size. Nothing appears in the dropdown menu except standard crop sizes in inches.

Have you tried entering the numbers with the suffix "px" in the entry fields?
